Ricky has a lightbulb that he would like to image on a whiteboard, using a convex lens with focal length 35.0 cm. He has already mounted the bulb (with a filament 2.50 cm in height) at a distance of 1.95 m from the whiteboard. Where should he position the lens, to form a focussed image of the lightbulb filament on the board? Screen/ (Picture is not drawn to scale!) Image

Question

Please show the supported ray diagram, as well as all the three "standard rays"

 

This question deals with a simllar situatlon as shown In the vldeo demonstration during lecture 33.

35.0 cm. He has already mounted the bulb (with a filament 2.50 cm in height) at a distance of 1.95 m
from the whiteboard. Where should he position the lens, to form a focussed image of the lightbulb
filament on the board?

Complete solutions must show your work and include all of the following:
• Statement/labelling of all distances.
• Numerical answer giving the distances from the lens to the lightbulb and lens to the screen.
• A supporting ray diagram, using this location of the lens and the object and image locations. The
ray diagram should clearly show the paths followed by all three "standard" rays.
• A comparison between the results of your numerical calculations and your ray diagram:
o Isthe image upright or inverted?
o Is the image real or virtual?
o What is the magnification of the image with respect to the filament?
If there are multiple locations at which Ricky can position the lens and form an image of the filament on
the board, provide these answers for each possible location of the lens.
